Hi,
I´m new to Oracle RAC and worked most of my life with Oracle single node instances.
I´ve downloaded Oracle 11.2 std edt and was planning to do a test install on two serveres.
I´ve started to read through Oracle guide but there is two things I´m confused about up to now.

Do I need to install Oracle Grid Infrastructure when using 11.2 Standard edition?
To use ASM do SAN diskgroup need to be RAW?

Am I missing anything here?
Also I got a friend to create a partition on the SAN as RAW device. I was thinking this was a req for ASM but then I read:

If you upgrade an existing Oracle RAC database, or an Oracle RAC database with Oracle ASM instances, then you can use an existing raw device partition, and perform a rolling upgrade of your existing installation. Performing a new installation using raw devices is not allowed.

Please some help.. I´m stuck on the basics and just need some guidance to get me started.
